RAIL ANCHOR.

original application filed January 27, 1921, SeralNo. 440,396. Divided and this application lei May 17, i922. serial Nb. 561,579.

Be it known that l, LAURENCE d. Birmin- LEY, a citizen of the United States, residing at Milwaukee, in the county of lililwaukee and State of Vilisconsin, have invented certain new and useful Improvements in Rail Anchors, of which the following is a specilication.

My invention relates to devices for resist-v ing the tendency of railroad rails to move longitudinally, such devices being known generally as rail anchors, rail stays and antiereepers.

The object of the invention is to provide an anchor device suitable for resistinglongitudinal creeping movement of railroad rails which will be relatively inexpensive to manufacture, conveniently applied to a rail, and which when applied will take a combined spring grip and shackle hold on the rail.

A further and more specific object is to provide a novel anchor of the two-piece7 type consisting of a spring yoke member adapted to be strained during its application to a rail so as to exert a spring grip on the rail, and a jaw member having an interlockA ing engagement with the spring yoke inembei' and formed of metal having sutlicient resiliency, whereby it will yield to permit :in angnlarly disposed portion thereof to be forced over the edge of the rail base and snap into engagement with the upper snrface of said base, thereby, locking both mem-v bers of the device onthe rail so as to prevent accidental displacement of the parts of the device, or the displacement of the device on the rail.

The invention has for further objects such other new and improved structures and combinations of parts hereinafter described and claimed, for carrying out the above' stated objects and such other objects as will appear from the following description of the invention, as illustrated in the accompany drawing. Y

In the drawing: y

Fig. 1 is a plan view of a rail anchor constructed in accordance with my invention illustrating the manner in which the same is applied to the base flanges of a rail.

Fig. 2 is a side view in elevatQI?L Of the of the vjaw anchor device,` illustrating it in the same relative position as shown in Fig.' 1, and

Fig. 3 is an,` end view in elevation of' the j aw end of the anchor showing the same in its normal 'appliedposition.

Like characters of reference designate corresponding parts in the three figures of the drawing. A i

Referring to the drawings, the base portion of a railroad rail is indicated the reference character 10 and one of the ycross ties on which the rail is supported isA indicated by reference numeral 11. l

The preferred embodiment of rail anchors illustrated in the drawing, consists of" a yoke member-'12 and a jaw member 13 which have an interlocking engagement with eachother and together embrace the base flanges ofthe rail. vThe yoke rmember 12 `is preferably formed of spring metaland is provided at one end with an angularly disposed hook 14 providing jawwhich fits over one "edge of the rail base and atthe other end with an upstanding portion 15 which engages a portion of the outer surface of the jaw member 13 and interlocks therewith'.

rllhe jaw member 13 is made, preferably of spring metal and consists of a Hat, vertically disposed body portion 16 pro-vided on its forward and rear edges with angularly disposed lugs 17 and 18, respectively, which project over and ragainst the upper surface ofthe rail base.v The upper edge ofthe lug 17 is preferably formed `with a cam lsurface 19 to facilitate the application'of 'the anchor to arail, as will be hereinafter described. The lower edges of both lugs 17 and 18 are preferably tapered to conform with the-in# clination of the upper surface of the rail base. The ylower edge ofy the lug 18, in addition to` being tapered, isralso sharpened, as indicated at 20, or' lotherwise suitably provided with a sharp edge adapted to take a biting hold on the rail. The forward end member '16 is bent inwardly to provide a tie abutment 21, which vabutment 'projects under therailbase 'and bears against one of thevertical facesfof the cross tie 11y when the anchor 'is' in 'its applied Ps.- lion' H 'flesled the'tj 'abutting flange 2i may be rigidiiied by forming thefliange and body portion of the'javv ineinber'with-acor-V ioo rugation 22 which extends around the corner 23 of said member.

The body portion of the jaw member is formed with a relatively long slot 24; and a shorter slot 25 connected therewith, through which the end 15 ofthe yoke member extends when theY yoke and aw members have their interlocking position.

in applying the anchor to a rail7 the jaw 1411 of the yoke is fitted over one edge of the `rail base, and the angular lug 1S of the jaw member 13 is tted over the opposite edge of the rail base, as shown in Figs. 1 and 2. '1n this position of the yoke and jaw mem- --bers 'the end l5 of the yoke member may be passed through the relatively long slot 24 of the jaw memberl iand thenmovedinto the shorter slot j25, which position the upstanding projection 15 of the yoke will extend above the upper edge 26 of the slots,

so as to effect an interlocking engagement vbetween the yoke and jaw members. The gaw member 13 may then be raised to the position shown 1n Fig. 3, during which movenient the cam surface '19 of the lug 17 willr bear against the edge of the railA and thereby flex the spring metal jaw member sufiiciently v. to permit the said lug 17 to snap over the upvper edge of the rail base.

vably assumes a position dia y l Theraising of the jaw `member 13 from the position shown in Figs. 1 and 2, to the position shown in F ig. Ssubjects the spring yoke 12 toa torsional strain, whereby the hook portion 111, whichl preferably extends in a direction away from the'cross tie, isy forced downwardly against the upper surface of the rail base and the body portion of the yoke at this end exerts a spring pressure against the under surface The tensioning` of the Aspring yoke member 12 in this manner7 the spring grip produced thereby against the upper and lower surface of the rail base, provides an effective resistance to the tendency I y of the vibration of the rail, or other disturbing influences, to loosen theinitial griprof the device on the rail. When the device is 11i-its applied position, the yoke 12 prefergonally across the base of the rail, 'so that vthe -device as a 'whole `will take a iirm shackle hold on the opposite edges of the rail base when the rail is subjected to a creeping pressure.
